Families from surrounding ranches and properties without carrier delivery routes make the drive to Millican. The post office sits near the intersection of FM 159 and the rural landscape between Bryan-College Station and Navasota. There's no city carrier service here. Instead, one rural route and one general delivery route handle what street delivery exists, though 171 PO Boxes dominate the mail system.
The ZIP code covers 2.86 square miles of land with a median age of 36.5 years. Hispanic residents make up 5.6% of the small population, and the community has no commercial establishments in recent business data. This isn't a town with a main street. It's a scattered rural area where a post office provides the central gathering point.
Neighboring subdivisions like Seven Eleven Ranches and Lake Ridge Estates sit 1.5 to 2.5 miles away. Residents from these areas often use Millican's post office, explaining why PO Box counts far exceed local households. The facility operates as a regional mail hub for communities too spread out for conventional carrier routes, serving an extended service area across this part of Brazos County.
With only FM 159 showing carrier route records, Millican's street infrastructure reflects its status as a rural crossroads rather than an incorporated town. The single farm-to-market road handles what limited street delivery exists, while the post office serves as the primary mail distribution point for the surrounding region.
